APPARATUS FOB TBEATING OILS.

Application'led June 8, 19121,` Serial No. 475,862. -Renewed February 5,1927.,V

This invention relates to improvementsin apparatus for treating Voilsand refers more particularlyto an apparatus inwhich the carbon whichl isseparated'from the-oil in the vaporization thereof is concentrated inthe carbon pots situated in one end of the expansion or vaporizingchamber.

Among the salient objects of the invention are to provide an apparatusin which the oil is introduced to the .expansion chamber in the oppositeend from that at which the` vapors are relieved therefrom, -therebypermitting a longer period.` of time for the vaporizing reaction to takeplace and causing the more heated oil to permeate and Work back throu hthe cooler oil through the reactin period; to provide an apparatus inwhich t e vaporizin chamber is shaped to form a carbon' pot wherein thefine particles of separated carbon collect and are drawn off therefrom;to provide an ap aratus which is more easily cleaned in t at the carbonis concentrated in the relatively restricted portion of the vaporizingchamber.

The sin le figure is a diagrammatic side elevational view of theapparatus.

Referring in detail to the drawings, the oil to be treated is introducedthrough the inlet pipe 1 `regulated by a valve 2 and is charged bymeansof a pump 3 throu h the .line 4 to the heating tubes 5 `whc "aremounted in a furnace 6 heated by means of gas burners 7. The oil afterbeing raised to a cracking temperature, passes through the transfer lineinto the expansion chamber 8 which transfer line extends substantiallythe ventire length of the expansion or vaporizing chamber as shown at 9.The oil which has been heated to a reacting temperature in the heatingzone is thus introduced linto the opposite end of the vaporizing chamberfrom that at which the transfer line enters'. As the oil passes into thevaporizing zone. there is immediately a free carbon separation -`as iswell known and this free carbon tends to settle and collect into thecarbon leg 8 of the vaporizing chamber. It is a well known fact in thecracking art that at a point where the transfer line discharges oil intothe vaporizing chamber, there collects the greater portion of the fre'ecarbon which is deposited' out of the oil in the vaporizing chamber. Bintroducing thejoil as shown this carbon will tend to colle-ct with theheaver residual heavier and .high boiling .the lighter vaporousfractions which collect 'in the upper' art of the vapor 4chamber and aredrawn o through the riser 12 which is' connected to a dephlzegmator 13.Aftenbeing reiluxed, the uncondensed portion passes over. through theline 14 regulated by a valve 15 to a water condenser 16, theliquiddistillate therefrom assing down through theline 17 regulatedp by avalve 18 to the receiver '19 where it may be drawn olf through theliquid drawof line 20 controlled by a valve 21. Pressure on the stem isdesignated by pressure gauge '22; t is pressure may be positivelyregulated by pressure relief valve 23. Liquid level gauge 24 designatesat all times the height of the liquid in the receiver. The retluxfromthe dephlegmator may be returned in regulated quantities through thereflux line 25 controlled by a valve 26 to the charging line 4 where itis reintroduced to the heating zone for further treatment.

An additional featureV of importance in the vaporization of the oil `isthe fact that the vapors which are released from the oil immediately onits being introduced to the vaporizing chamber, must pass over and incontact with a considerable oil body in the expansion zone in theirtravel to the riser 12 through which they pass off into thedephlegmator. By causing the vapors to pass substantially the entirelength of the vapor chamber in this manner, the vapors are 'ven ampletime to separate out the undesirable fractions in the expansion chamber.These int oils pass down into the carbon leg and)0 may be drawn' offwith the free carbon as residuum. We claim as our invention:

1. In an oil distilling a paratus, an elon' gated horizontally dispose.expansion chamer, a conduit for heated oil passing from one end of saidchamber substantially` through the same and discharging the oil at theopposite end thereof, said chamber hav ing a vertical leg at thedischarge end of said conduit, a vapor outlet positioned away from thedischarge end of the conduit for discharging vapors from said chamber, a

dephlegmator .communicating with said outlet and a residuum dischargefrom said leg.

2. In an apparatus for treating hydrocarbon oils, the combination withmeans for ',charge end of the condult, a vapor outlet leading from theexpansion cham er positioned away from the discharge end v4of said con--duit, and a dephlegmator communicating with said outletl '3. In an oildistilling apparatus, an-elonated horizontally disposed reactionvchamer, a closed means for passing heated oil from one end of saidchamber substantially vthrouwh the same, and discharging the oil intothe chamber at the opposite end thereof, said chamber havin a legadjacent the discharge end of said c osed oil carrying means, means forvdischarging vapors from the chamber positioned at a point remote fromthedischar efendfof the closed oil carrying means, dep egmating meanscommunicating with said vapor discharge means and residuum drawoi meansfrom said leg.

4. In an oil distilling ap aratus, an enlarged reaction chamber, a osedmeans ,for Y conveyinlheated oil substantially complete- 1y throu thesame, said means permitting the disc arge of the 'heated oil into the,chamber at a' point lremote from that at which'lsaid closedmeans entersthe reaction v.

chamber, said chamber being provided with a downwardly extendingenlarged portion adjacent the point of discharge of the oil from saidclosed means into said reaction chamber, a vapor outlet leading from theA reactionl chamber at a (point remote from sald enlarged portion ancondenslng means in communication with sald vapor outlet.
